IMPROVEMENT IN MOUTH-PIECES FOR MU$ICAL lNSTRUlVlENTS.

Specification forming part of Letters Patent No. 190,55Q, dated May 8,1877; application filed March 22, 1877.

To all whom it may concern:

Be it known that 1, Cinemas G. GoNN, of Elkhart, in the county ofElkhart and State of Indiana, have invented certain Improvements in theConstruction of Mouth-Pieces for Musical Instruments, of which thefollowing is a specifica ion:

This invention relates, first, to certain improvements on the,mouth-piece for which I obtained Letters Patent dated 23d of February,1875, No. 160,164, and consists in forming within the annular recess ofthe mouthpiece of musical instruments any desired number ofindentations, grooves, or raised surfaces, in which the vulcanizablegum, constituting the outer surface or rim of the mouthpiece, is allowedto run, causing, by its adherence thereto, the permanent fixing withinthe recess of said gum. I

My invention consists, secondly, in providing the face of themouth-piece of musical instruments with a coating of rubber or othervulcanizable gum hardened to any desired degree.

In the accompanying drawing, Figure l is a longitudinal section on theline 1 1, Fig. 2, of a mouth-piece ready for the reception of the rubberrim. Fig. 2 is a front view of the same. Fig. 3 is a longitudinalsection on the line 3 3, Fig. 4, of a mouth-piece with the rubber rimapplied. Fig. 4 is a front view of the same.

In carrying my present invention into operation, I prefer to proceed asfollows: Within the annular recess a of the mouth-piece or emboucheredescribed in my patent above re ferred to, I form, by a lathe or othersuitable means, a groove or a series of grooves, indentations, or raisedsurfaces, 12, either alone or it the required shape and position. Thewhole is then placed in a vulcnnizer and the gum vulcanized to anydesired degree in any ordinary manner by heat, either with or withoutpressure.

By the means above described I am enabled to secure the perfect adhesionto metallic or other surfaces of either india-rubber, guttapercha, orother vulcanizable gums, and by curing the same to either a hard or softcondition after its application to such surface, I produce an articlethat will stand a very considerable amount of wear or use withoutbecoming loose or breaking away from the surface to which it is applied.

Having thus described my invention, the following is what I claim as newand desire to secure by Letters Patent- 1. A mouth-piece for musicalinstruments, constructed with a rim of rubber or other vulcanizable gumsecured within a recess or recesses in the face, substantially as shown.

2. The improved mouthpiece herein described, providcd upon its face witha coating of hard rubber or other vulcanizable gum, substantially as setforth.
